How to Choose a Pillow for Your Sleeping Position
January 2026 · 6 minute read
Pillow advice usually starts with material. It should start with position, because position determines how much vertical space there is between your mattress and your head, and that space is what a pillow is filling.
Get the height wrong and no amount of premium foam saves you. Get it right and a fairly ordinary pillow performs better than an expensive one.
Side sleepers need the most height
Lying on your side, the gap to fill runs from the outside of your shoulder to the side of your head. It is the largest gap of any position, and broader shoulders make it larger still.
Too little loft and your head drops toward the mattress, closing the angle on the underside of your neck. This is the position most associated with waking up with pain running from the neck into the shoulder.
Back sleepers need moderate height
On your back, the gap is smaller: the back of your head is closer to the mattress plane than the side of it is. A pillow built for side sleeping will often push a back sleeper's chin toward their chest.
What back sleepers do need is support under the cervical curve specifically, which is where a contoured shape does more than extra height.
Combination sleepers should size for their side
If you change position through the night, choose for the position that needs the most support, which is almost always side sleeping. A contour profile handles the switch reasonably well because the neck ridge is available in both positions.
Front sleepers are the exception
Sleeping on your stomach forces your neck into rotation regardless of the pillow, and a contour makes it worse rather than better. A very low, soft pillow is the usual compromise, and gradually retraining toward side sleeping is the better long-term answer.
A one-minute check
Lie down on your current pillow in your usual position and ask someone to look from the front.
- Is your nose in line with the centre of your chest?
- Is your chin neither tucked down nor tipped back?
- Is there a visible gap under the curve of your neck?
- Do you need to fold or add anything to feel supported?
Matching this to a size
Nidra's cervical contour pillow comes in three sizes with published dimensions and loft, from a 4 inch thickness up to 5 inches, so a smaller back sleeper and a broad-shouldered side sleeper are not buying the same height. If you are between two, the size guide on the product page is the place to start.
Nidra makes one product: a orthopedic cervical pillow with published loft, foam density and cover specifications, in three sizes.
